SWIVEL SOCKET.

Application filed June 25, 1924.

To (all *whom 27!; 7IZL]/ concern:

Be it known that I, ELMnR M. RAY, a citizen of the United States,residing at Hour iny, in the county of Osage and State of Oklahoma, haveinvented new and useful In'iproveinents in Swivel Sockets, of which thefollowing is a specification.

This invention relates to swivel sockets ot' the character used in welldrilling operations. and has for one of its chief charactcrist-ics theprovision 01. a device wherein the seat for the movable socket membercan be quickly and conveniently removed from the body of the device whenit becomes damaged beyond further use, and replaced by a new one at theplace where the device is in use, thus eliminating the necessity oftaking the device to a machine shop for this purpose.

In carrying out the invention I also provide the body of the device witha plurality of slots and openings, through certain oi which the seat canbe examined from time to time, and through others of which the bottom ofthe device can be cleaned as the occasion may require.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicute similar parts in the several views, and whereinFigure 1 is a view in elevation of the device forming the subject matterof the in vention.

Figure 2 is a sectional view taken on line Q---'2 oi Figure 1.

Figure 3 is a sectional view taken on line ii- 3 of F i gure 9.

liigurc i is a sectional view if-ii.- of Figure 2.

Referring to the drawing in. detail 10 represents the body of the devicewhich is preferably of cylindrical contour in cross section, except forthe reduced squared portion 11 provided to permit the use of a wrenchfor the purpose of holding the body steady for a purpose to behereinafter detaken on line scribed. It will be noted upon inspection ofFigure 2 that the body is formed with a longitudinal bore, divided intoupper and Serial No. 722,417.

lower portions 12 and 13 respectively, and an intermediate portion let.The upper portion 12 is relatively small and adapted to receive theoperating cable not shown, while the lower portion 13 has a diameterconsidcrably larger than the upper portion 12, and receives the socketmember 15, which is arranged in the lower portion 13 of the bore forboth sliding and rotatable move-- ment. This member 15 is formed withthe usual socket 16 to receive the knotted end or the cable, not shown,or said cable may be associated with the socket member 15 in i any wellknown manner. The bore in the socket member 15 is formed with grooves 17into which a portion oi the cable projects to make a tight fit betweenthe cable and said socket member 15. The lower portion 13 of the bore isinteriorly threaded as at 18 to accommodate the particular tool to heused in connection with the body portion 10. The intermediate portion14: of this bore has a diameter greater than the upper portion 12, butless than the lower portion 13. and is adapted to receive the seat 19for the socket member 15, which seat is of a size to be snugly fittedwithin said intermediate portion 1 1 as clearly shown in Figure 9.. Theupper end of the socket member contacts the adjacent end of the seat 19,which seat protects the body portion from wear incident to the use ofthe device. It will. now be noted that the body portion 10 is formedwith spaced slots 20 and 21 through which the socket n'ien'iber as wellas the cable can be examined from time to time, and through which theseat 19 can also be examined. F or this same purpose I provide the bodyportion 1.0 with an opening 29. which. is arranged at a pointapproximately midway between the ends of the seat 19 when the latter isin its normal condition. lVhen the seat has become worn so that thelower end oi" the seat can. be seen through the opening 22, the saidseat can be easily and quickly l'Q-DIOVQCl, and replaced by a new seatwithout the necessity of carrying the device to a n'iacl'iine shop forthis purpose. In other words this work can be accomplished at the placewhere the device is;

being used, as it is only necessary to support the body 10 by a wrenchwhich is used in conjunction with the squared portion 11 of the bodyportion and above referred to. After the wrench has been placed on thebody portion 10, the cable above referred to is slackened to allow thesocket member 15 to be lowered beyond the lower end of the body portion10, after the tool above referred to has been separated from the bodyportion. Then any suitable instrument can be. inserted through theopening 22 to force the worn seat 19 from the intermediate portion 1a ofthe bore, into the larger lower portion 13 thereof, through which itwill readily fall to the open end of the body portion. The body portionis also formed with an opening 23 adjacent the lower end thereof whichis used for the purpose of cleaning the body portion 10 as the occasionmay require.

lVhil'e it is believed that from the foreg'oing description, the natureand advantages of the invention will be readily apparent, I desire tohave it understood that I do not limit myself to what is herein shownand described, and that such changes may be resorted to when desired asfall within the scope of what is claimed.

What I claim is:

A device of the character described comprising a body portion having alongitudinal bore threaded and slightly tapered adjacent the lower endthereof, the opposite sides of the body portion for an appropriate partof its length being flattened to acconiinodate a tool for turning saidbody portion, said bore being divided into upper and lower portions ofrelatively different diameters, and an intermediate portion of slightlyless diameter than the lower portion, and slightly greater than theupper portion, a socket member slidably and rotatably fitted in thelower portion of said bore, a seat snugly fitted within the intermediateportion of the bore and adapted to he engaged by the socket member. saidseat being capable of being removed from the body portion through the.lower end of said bore, said body portion having sight openings at theopposite sides through which said end socket member can be examined,said socket having a longitudinal bore formed with spiral grooves toprovide for an effective grip on the cable for the socketmember.

In testimony whereof I aiiiX my signature.

ELMER M. RAY.
